What is it?

DL-Phenylalanine is the combined left and right isomers of the essential amino acid, phenylalanine. Each capsule contains 500 mg of dl-Phenylalanine (free form,) and Vitamin C (Ascorbyl palmitate) 10 mg. Other ingredient is vegetable capsule.

According to the manufacturer:

"dl-Phenylalanine is a combination of the well-tolerated essential amino acids, d- phenylalanine and l-phenylalanine. Together, these compounds promote mental functioning, support a positive outlook, and relax the musculoskeletal system. l- Phenylalanine is a precursor to tyrosine, which converts to the neurotransmitters norepinephrine, epinephrine, dopamine and tyramine. Tyrosine and its metabolites may support emotional well-being, memory and learning. d-Phenylalanine may promote the levels of certain endorphins, thereby calming stressed muscles and joints.

By maintaining healthy tyrosine and endorphin levels, dl-phenylalanine nutritionally supports mental acuity and emotional well-being, while relaxing stressed muscles and joints."
